Hi, I'm kind of new to this forum, but I grow sweet potatoes every year in Wisconsin, zone 5. I've grown the Georgia Jet, Centenial, and Boregard, all with good results. I like the centenial best. I had a Georgia Jet the size of your head. Main thing I do is losten the soil very well and deep,till in lots of compost. make a mound and cover it with a plastic mulch. (I add a bit of steamed bone meal to pormote root growth) Plant the slips (around Late May here) and let them grow, they need to be watered especially if the season is dry. After the first frost in the fall I dig them. Most take about 90 to 100 days of growth. I have one left from last year's crop, which I'm going to try to spout and raise my own slips. I've watched a few U tube videos showing how to do that. Hope it works. Anyone have experience with that?
